The Optimization Research on the Mechanized Production Model of Rice-Wheat Rotation

Rice-wheat rotation is one of the principal planting patters of rice and wheat in China. Research on mechanical production model and economic benefit of rice-wheat rotation can further optimize the production model. The paper defined rice-wheat rotation region of China and divided the region into three parts including developed area in the east coastal, major grain producing area in midland, less-developed area in southwest. Study out 10 typical mechanization production models in rice- wheat rotation region by analyzing the present situation. Then compare the models at the cost, output value and proceeds. Analyze the trend of different areas on the principle of efficiency, economy and equipment practicable.
